We're collecting photos with our DJI Mini 2 for the purpose of creating ortho-photos and/or 3D-models. We're flying at 100m and overlap typically 80/75% to get a final resolution of approximately 2-3cm/pixel. Multiple GCP;s are spread around the project area.
When importing photos in blocks to C-C, photos are shown as if they where taken horizontal, not vertically as they actually are. It's when looking at the project photo block in the 3D-view we realise all cameras are pointing forward and not downwards. Seems like there is something missing in the photo metadata but they are imported straight from the drone SD-card including position data from the drone GPS, flight control and camera.
Anyone experienced this and know whether it affects the final aerotriangulation or if there is a way to fix this?
I've noticed it's impossible to point out our GCP;s on the photos before running a first A-T without the GCP;S. Then, after that's been run, I may add the survey data and get a suggestion from C-C on what pictures to point the GCP;s out. There are between 2000 and 3000 photos in the project, so not possible to search manually for potential matches between GCP;s and photos showing them.
Sorry for my bad grammar and spelling!
